TO ALL WHOM IT. MAY CONCERN:

Be it known that I, C. .W. BREWER, of Racine, in the county of Racine, and State of Wisconsin, have invented a new and improved Piano-Hammer; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enablethose skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- The drawingis apespectiye view of my improved hammer.

The object of this invention is to obviate the so-calledbeil-tones, which resultwhen the lower octaves of a square piano are struck with force. y

This objection exists in almost every square piano, and piano-makers have long sought to obviate it.

This I have perfectly accomplished by means of a soft-rubber tube or volute inserted in -the felt portion of the modern felt and bnckskin hammer-head, and by this composite head have produced in the head the proper elastic action of the whole head, the said action ,pervadng the felt and buckskin parts with elastic waves of different quality, which compound action produces the clear, rounded tone when the hammer is struck upon the strings, thus obviating the prolonged ringing or bell-tones, so called, which'are objectionable.

I am aware that hammers have been made with. a rubber tube combined with the old buckskin hammer, the tube being in contact with'the wooden part of the hammer-head, and the huckskin wrapped over the tube.

This device is well known to the art as being imperfect, arid of less value than the modern felt and buckskin hammer; but the rubber tube or volute, when combined with thefelt alone, `or felt and buckskin, in the manner shown in the accompanying drawing, does produce the desired effectof rounding and closing the tones of the lower octavos when struck forcibly.

In the drawings- A is the stem.

B, the wooden head, on which the buckskin, d, and felt,`b, ,of the modern hammer are' aiiixcd.

a is the rubber tube or'volute, passing through and surrounded bythe felt.

I claim as new, and desire to secure by Letters Patent- A piano-hammer, constructed substantially as and for the purpose setforth.
